I can give you a small snapshot from the group I interviewed with last week. Earliest date offered was June 25, and I believe several people took it. Myself and at least one other person took late August/early September dates, although I'm hoping to be able to take an earlier class if I can make it work with my career transition from my "normal" job and cross country move to my wife's new post with the Army.

We were told to expect 6 weeks in Appleton (5 for those that already have an ATP) for systems/CPT followed by 2 weeks of sims with IOE to follow. Best case would probably be 3-4 months from start of class to off IOE.
